how do i spray paint furniture so it feels smooth?

I'm trying to spray paint a desk from a dingy white to a semi-gloss white. I used a primer and let it dry for about 24 hours. Afterwards, I used the semi-white spray paint and applied one coat so far. The problem I'm noticing is that, when I move my hand over the painted areas, it's very bumpy. What should I do?

use a high number sandpaper or an old scotch pad (my particular favorite, but it has to be almost worn out) to buff the roughness off the chair....Thoroughly dust the chair to remove any of the particles, and then apply the next coat.... Sanding between coats is a familiar thing to many people who paint "nice" objects. without a special paint booth it's often difficult to maintain a perfectly dust free environment. Another thing...Is the paint going on smooth? If not, there's problem with the paint, a gummed nozzle, or your technique. Regarding technique, many paint to close and the paint runs...to prevent that, the next time they paint, they paint too far away. that can cause a bumpy surface...the nozzle and paint issues I can't really address. I do alwasy paint a test coat onto scrap to make sure that the paint is flowing well, and consider 2 -3 coats to get a full cover better than painting in one fell swoop. Finally, the environment can play a part...That is, if you're painting in the wind, and/or on a hot day in the sun, the paint can actually dry partially while it's traveling thru the air or collect dust, both of which can cause the bumpy feel. best wishes

thanks everyone! i was told not to sand the furniture because it's just some cheap ikea veneer, as opposed to wood, so greater the chance i would damage the whole thing. i ended up spraying a couple extra coats (3 to be exact) and unfortunately no better results. oh well! looks alright, just as long as you don't run your hand across it! eek!
just give it a gentle sanding...I think you'll be pleased with the result...you're not sanding the wood, just the paint.

You have to start with a smooth surface. Then sand lightly between coats. If the spray paint still ends up bumpy then either the humidity is too dry or the temperature is too hot or you may be holding the can too far from the desk. Spray paint needs to be wet when it hits the surface so it can coat and run together (without running off the surface) and any of the above conditions might be letting the paint dry too much before it hits the surface and smooths out. Good luck.

Oil based of latex based? Oil based lays out nicer than latex's do. Plus, if you are using oil, besides sanding between coats, try reducing the paint by about 10% with the appropriate thinner. I spray day in and day out, though most my paints are epoxies and polyurethanes. A 10% reduction gives a nice finish in most cases.

Did you sand the primer? I used spray paint several times and when I sprayed a car, it was very smooth. Try sanding like what seandouge said
